请问可能的问题是什么呢？我应该如何解决这个问题？
首先，我的class是这样的一个简单的class
public class Restaruant {
private String restName;
public void greetCustomer() {
if(restName == null) {
System.out.println("Wellcome to our restaruant!");
} else {
System.out.println(restName + ": Wellcome to our restaruant!");
}
}
private String getRestName() {
return restName;
}
private void setRestName(String myName) {
this.restName = restName;
}
}
然后我在配置文件里写了
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://www.springframework.org/schema/beans
http://www.springframework.org/schema/beans/spring-beans-4.0.xsd">
最后我的主程序是这样运行的
public class TestSpringObject {
public static void main(String[] args) {
ApplicationContext context =
new ClassPathXmlApplicationContext("SpringConfig.xml");
Restaruant restaruantObjRestaruant = (Restaruant) context.getBean("restaruantBean");
restaruantObjRestaruant.greetCustomer();
}
}
得到的问题是这样的：

Does the parameter type of the setter match the return type of the getter?

问题已经解决了， 是我的get和set方法是private的问题。在解决问后，新的问题出现了。打印出来的结果如下：
Wellcome to our restaruant!
我不能理解为什么。应该是要打印我给它注入的Pete的问候才对的呀。
刚刚看了一下get 和 set的parameter，发现了我写的粗心了。问题已经解决了，真是抱歉，大侠们辛苦了。
